The PS/2 486DX-33 Processor Upgrade for Model 70 (16/20MHz) or the PS/2 486DX-33 Processor Upgrade for Model 80 (16/20MHz) can be installed when computing power demand increases on the following systems: o PS/2 Model 70 (8570-E61, 061, 081, 121, 161) o PS/2 Model 80 (8580-041, 071, 081, 111, 121, 161, 311 and 321). END USER PRODUCTIVITY Most hardware and software remain the same or enhanced in the user-friendly aspects. Noticeable performance increase is visibly achieved. When installed in the respective models (refer to the system configuration below), the upgrades are designed to maintain the user-friendly and interactive features, and the high productivity of the PS/2 family of systems. Depending on the application, these upgrades improve system throughput using BAPCo benchmark (SYSmark92), up to: o 97.32% and 100.40% for Model 70, 386 -- 16 based system with 4MB and 8MB memory respectively o 91.39% and 91.20% for Model 70, 386 -- 20 based system with 4MB and 8MB memory respectively o 91.19% and 92.54% for Model 80, 386 -- 16 based system with 4MB and 8MB memory respectively o 81.79% and 85.01% for Model 80, 386 -- 20 based system with 4MB and 8MB memory respectively. The processor upgrade enhances end-user productivity by maintaining hardware and software compatibility with the base system, features and applications. The common user interface enables significant performance enhancements and increased productivity without new education, commands or unique instruction sets.
